Glue ear

Introduction

Glue ear is a common childhood condition in which the middle ear becomes filled with fluid. The medical term for glue ear is otitis media with effusion (OME).

It's estimated that one in five children around the age of two will be affected by glue ear at any given time, and about 8 in every 10 children will have had glue ear at least once by the time they are 10 years old.

The main symptom of glue ear is some hearing loss in one or both ears. This usually feels similar to what you experience when you put your fingers in your ears.

What causes glue ear?

The middle ear is the part of the ear directly behind the eardrum. It is made up of three tiny bones that carry sound vibrations from the eardrum to the inner ear. The build-up of fluid associated with glue ear prevents these bones moving freely, which affects hearing because it means they can't pass sound vibrations to the inner ear.

Exactly what causes this build-up of fluid is unclear, although it seems to be related to a problem with the tube that connects the middle ear to the back of the throat (Eustachian tube). One of the main functions of this tube is to help drain fluid from the middle ear.

It's thought that problems with the Eustachian tube may be caused by things like a previous ear infection, smoke irritation or allergies. Glue ear is not caused by getting water in the ear after swimming and showering or by a build-up of ear wax.

Growing up in a household where adults smoke, being bottlefed rather than breastfed as a baby and having siblings who have had the condition are also thought to increase the risk of glue ear.
